Grayson Thermal Systems supplies off the shelf and bespoke solutions

Travelling in perfectly temperature controlled trains, tramways and metros is key to the travel comfort of today’s passengers and drivers. Due to the harsh vibrations and ballast damage encountered by rail locomotives and light rail vehicles, Grayson’s products are designed using heavy duty components and tested in an environment replicating these operating conditions.

We are also an approved distributor of Thermo King air conditioning products for rail. All products can be supplied as aftermarket or OE solutions.

Our HVAC solutions, whether Grayson or TK manufactured, are highly reliable and deliver top performance while reducing operating costs.

These products are:

  • Driver’s cabin heater / screen defroster / air conditioning
  • Passenger ventilation units / HVAC units
